Silicone has unique material characteristics that enable parts to be molded with intricate features, significant undercuts, surface finishes, and tight tolerances. ProMed offers custom compounding to meet the performance essentials of your design.
From concept to existing production, whether your part(s) are simple or complex, ProMed’s highly qualified technology staff can assist you in your project. Various molding processes consist of:
Liquid Injection Molding (LIM)
This process utilizes a liquid silicone rubber which results in a short molding cycle enabling a cost-effective part. This material and process is typically used for medium to high production runs.
High Consistency Injection Molding
Very similar to LIM molding except the material is a high consistency rubber (HCR – “gum-stock” rubber).
Typically consists of “transferring” a high consistency rubber (commonly referred to as a HCR or “gum-stock”) silicone from the exterior of a mold through a sprue and runner system into the cavities of a mold.
RTV (Room Temperature Vulcanization) Casting
ProMed has developed the ability to compound and deliver 2-part RTV compounds in a closed delivery system.
A common definition for a micro-molded part is typically a part with a mass of 1 gram or less or a part with a total volume of less than 0.003 cubic inches. To put this in perspective, a micro-molded part can be smaller than a piece of rice or a resin pellet.
